NHTSA Complaint #11494996 — 2011 CHEVROLET SILVERADO 1500

The worst problem I have with this vehicle is that it will cut power to propulsion without any warning. I was driving down a suburban roadway, not on the freeway, thank God. When the truck's automatic gear shift wouldn't engage, I went from going 30 mph to 5 mph in seconds. The accelerator pedal wouldn't respond, I managed to coax my truck into a parking lot and restart the engine. Other times the head lights will not come on. Just today, I turned on the left turn signal and the Stabilitrack warning light came on, plus the radio made a brief noise of static. This particular issue appeared and disappeared in one second. I'm concerned that these problems are a manufacturer's mistake, and I want it fixed as soon as possible. My mechanic has tried repeatedly to find the cause but has been unsuccessful.
